Technical Field

[0001] The present application relates to the technical field of cyclones, and in particular to a cyclone. Background Art

[0002] Cyclones are widely used in industries such as petroleum, chemical industry, metallurgy, coal, electricity, medicine and cement. They use centrifugal force to separate dust particles from the airflow. The flue gas flow enters the backlog distribution chamber from the inlet. After the airflow is buffered and decelerated by the backlog, it is distributed to each cyclone. The airflow accelerates in the cyclone and forms a certain angle with the inner wall of the cyclone. It enters the cyclone chamber and rotates. Under the action of centrifugal force, the dust in the flue gas is separated from the gas.

[0003] However, after long-term use, a lot of dust particles will adhere to the inner wall of the cyclone. It is inconvenient to clean the dust particles and impurities on the inner wall of the common cyclone. These dust particles and impurities will increase the air flow resistance, reduce the working performance of the cyclone, and affect the dust separation effect. In addition, the impurities attached to the wall of the cylinder will cause corrosion to the wall of the cylinder, reducing the service life of the cyclone. Summary of the invention

[0025] like Figure 1 and Figure 2 As shown, the present application provides a cyclone, comprising a cyclone body 1, an air inlet 2 is provided on one side of the upper part of the cyclone body 1, an air outlet 3 is provided on the top of the cyclone body 1, and a dust outlet 4 is provided on the bottom of the cyclone body 1. After the smoke enters the cyclone body 1 from the air inlet 2, it rotates along the inner wall of the cyclone. Under the action of centrifugal force, the powder ash in the smoke is separated from the gas, the dust flows out from the dust outlet 4, and the gas flows out from the outlet. A connecting cylinder 5 is provided in the cyclone body 1, and the upper end of the connecting cylinder 5 is fixedly connected to the top inner wall of the cyclone body 1. The connecting cylinder 5 is located in the middle of the cyclone body 1 and is connected to the air outlet 3. The lower end protrudes outward to form an annular support portion 51, and a cleaning component 6 is rotatably arranged on the connecting tube 5. The connecting tube 5 can support the cleaning component 6 under the premise of ensuring air outlet. A driving component 7 for driving the cleaning component 6 to rotate is arranged outside the cyclone body 1. The cleaning component 6 is driven to rotate by the driving component 7 to clean the dust particles and impurities attached to the inner wall of the cyclone body 1, thereby preventing the accumulation of dust particles on the inner wall of the cyclone body 1 after long-term use, resulting in increased airflow resistance, avoiding reduction in the working performance of the cyclone body 1, ensuring the dust separation effect, avoiding corrosion to the inner wall of the cyclone body 1, and extending the service life of the cyclone.

[0026] like Figure 2 As shown, the cleaning assembly 6 includes a sleeve 61, a connecting piece 62, a scraper 63 and a first gear 64. The sleeve 61 is movably mounted on the connecting tube 5. The scraper 63 is fixedly connected to the connecting tube 5 through the connecting piece 62. The scraper 63 abuts against the inner wall of the cyclone body 1. The first gear 64 is fixed on the sleeve 61. When the sleeve 61 rotates, the sleeve 61 drives the scraper 63 to rotate through the connecting piece 62, and the scraper 63 is used to clean the dust particles and impurities attached to the inner wall of the cyclone body 1.

[0027] like Figure 1 and Figure 2As shown, the driving assembly 7 includes a driving motor 71, a mounting seat 72, a first bevel gear 73, a second bevel gear 74, a transmission rod 75 and a second gear 76. The driving motor 71 is fixed to the top of the cyclone body 1 through the mounting seat. The first bevel gear 73 is fixed on the output shaft of the driving motor 71. The second bevel gear 74 is fixed to the upper end of the transmission rod 75. The first bevel gear 73 is meshed with the second bevel gear 74. The lower end of the transmission rod 75 extends vertically into the cyclone body 1. The second gear 76 is fixed to the lower end of the transmission rod 75. The second gear 76 is meshed with the first gear 64. The first bevel gear 73 is driven to rotate by the driving motor 71. The first bevel gear 73 drives the second bevel gear 74, thereby rotating the transmission rod 75. The transmission rod 75 drives the second gear 76 to rotate. The second gear 76 drives the first gear 64 to rotate, thereby rotating the sleeve 61, thereby rotating the cleaning assembly 6.

[0028] like Figure 2 As shown, a bearing 8 is provided at the connection between the transmission rod 75 and the cyclone body 1, and the bearing 8 reduces the wear between the transmission rod 75 and the cyclone body 1, prolongs the service life of the transmission rod 75, and makes the rotation of the transmission rod 75 smoother and more stable.

[0029] like Figure 2 As shown, a limit ring 9 is fixedly sleeved on the outer wall of the connecting tube 5. The limit ring 9 is located at the upper end of the sleeve 61 and abuts against the sleeve 61. The sleeve 61 is limited by the limit ring 9 to prevent the sleeve 61 from shifting upward during rotation, thereby making the rotation of the sleeve 61 more stable.

[0030] like Figure 2 As shown, two scrapers 63 are provided, and the two scrapers 63 are symmetrically arranged. The arrangement of the two scrapers 63 can improve the cleaning efficiency, and the arrangement of the two scrapers 63 balances the forces on both sides of the sleeve 61, thereby making the sleeve 61 rotate stably.

[0031] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
